JEI '+' button is only shown while items are missing about sophisticatedbackpacks HOT 1 CLOSED

Using

With an iron backup and pickup upgrade in the top slot, and a crafting upgrade in the bottom slot.
The crafting grid is open (right side) with the arrow pointed down (player inventory).

When I open a recipe in JEI for a 3x3 craft (haven't tried 2x2 or shapeless) - the '+' button is shown when I'm missing items for the shown recipe. But once I have all items the '+' button is just gone from the JEI recipe page.

Had another one written names MatthiasMann

I have a similar problem, only that I have no + at all when I select justenoughitems recipes and have the crafting field open in the backpack
I use the justenoughitems version
jei-1.19.2-forge-11.4.0.285.jar
and the version from sophisticatd backpacks

sophisticatedcore-1.19.2-0.5.15.142.jar

sophisticatedbackpacks-1.19.2-3.18.29.719.jar

from sophisticatedbackpacks.
